Stimulation of Anaerobic Fermentation of Wastewater and Sewage Sludge

This paper focused on determining the regularities of modern trends in the field of stimulation of wastewater and sewage sludge (SS) components transformation in anaerobic conditions with particular attention to the theoretical substantiation of the magnetic fields’ mechanisms field influence on these bioprocesses. The network system’s visualization and clustering of research areas of stimulation of anaerobic fermentation of wastewater and SS were carried out. The clusters were formed through a network: the red cluster conducted with the area of enzyme activity and use of various biostimulants for microorganism growth under anaerobic digestion and ecosystem bioremediation; the green cluster associated with general fermentation processes at the junction of aerobic and anaerobic conditions using different co-substrates; the blue cluster has generalized the use of methods of genetic modification of microorganisms used in anaerobic processes, including the digestion of SS, as well as the influence of minerals on the stimulation of fermentation. The analysis of visualization clusters was also devoted to studies on biostimulation of bacterial activity processes using a magnetic field. The generalized model of the magnetic field’s stimulating effect on bioprocesses was formed, which can be used in anaerobic digestion of SS and wastewater bio-treatment to produce useful bio-based products.
